OKX Integration & Protocol Analysis — OpenFinance / Web3

Technical Deliverables

• OpenAPI / Swagger complete interface specification
• Protocol and authentication analysis reports (API Key / Signatures / WebSocket auth)
• runnable source code (Node.js / Python) including auth, relays, caching, and error handling
• WebSocket / Webhook integration best practices and replay strategies
• Automated tests, sample requests/responses, and deployment guides
• Compliance and risk recommendations (KYC, data retention policies)

Example: Place Order & Callback (pseudo-code)

# POST /api/v5/trade/order
{ "instId":"BTC-USDT", "tdMode":"cash", "side":"buy", "ordType":"limit", "px":"30000", "sz":"0.001" }

# Recommended: after order creation, record clientOrderId and subscribe to order channel for fills
# Webhook: optional deployment to receive fills and fund movements (idempotent processing)

Example: RESTful Balance Query

GET /api/v5/account/balance
Header: API-KEY: <KEY>
Header: TIMESTAMP: <ts>
Header: SIGNATURE: HMAC_SHA256(<ts> + method + path + body, secret)

Response:
{
  "code":"0",
  "data":[{ "currency":"USDT","available":"1200.50","frozen":"0.00" }, ...]
}

# WebSocket real-time balance/position push
wss://ws.okx.com:443
subscribe: {"op":"subscribe","args":[{"channel":"account","instType":"SPOT"}]} 

Example: Order Placement & Callback

// Place order (pseudo-code)
POST /api/v5/trade/order
{ "instId":"BTC-USDT","tdMode":"cash","side":"buy","ordType":"limit","px":"30000","sz":"0.001" }

// Recommended: after creation, publish clientOrderId and subscribe to order channel for fills
// Webhook: optional deployment to receive fills and balance changes (idempotent handling)

Advanced Technical Recommendations

• Auth: Use timestamp + HMAC signatures; protect secrets and do not expose on the frontend
• Idempotency: Use clientOrderId to guarantee safe retries
• Replay / Data Consistency: Use order sequence numbers and tick-by-tick replay comparison
• Rate limiting: Implement token bucket and backoff strategies to avoid penalties
• On-chain reconciliation: Use a block explorer or own indexer to map on-chain events and funds
